Detailed Description

Typedefed as TreeModel::ConstRow.

TreeConstRow is a const version of TreeRow. TreeConstRow does not contain methods for modifying the underlying TreeModel.

Member Function Documentation

const TreeNodeConstChildren& Gtk::TreeConstRow::children

(

)

const

This returns an STL-like container API, for iterating over the rows.

See also Gtk::TreeModel::children() for the top-level children.

TreeIter<TreeConstRow> Gtk::TreeConstRow::get_iter

(

)

const

Gets a const_iterator to this row.

Returns

A const_iterator to this row.

template <typename ColumnType >

ColumnType Gtk::TreeConstRow::get_value

(

const TreeModelColumn< ColumnType >&

column

)

const

Gets the value of this column of this row.

See also operator[]().

Parameters

column

The model column.

Returns

The value of this column of this row.

template <typename ColumnType >

void Gtk::TreeConstRow::get_value	(	int	column,
		ColumnType &	data
	)		const

Use get_value(const TreeModelColumn<>& column) unless you do not know the column type at compile-time.

If the data output argument is of an inappropriate C++ type then this might fail at runtime.

Parameters

	column	The number of the column whose value you want to query.
[out]	data	An output argument which will contain the value of this column of this row.

Gtk::TreeConstRow::operator bool ( ) const

explicit

Discover whether this is a valid row.

For instance,

if (treerow)
  do_something();

Since gtkmm 3.22:

template <typename ColumnType >

const TreeValueProxy<TreeConstRow, ColumnType> Gtk::TreeConstRow::operator[] ( const TreeModelColumn< ColumnType >&  column ) const

inline

Use this to get the value of this column of this row.

This is a templated method, so the compiler will not allow you to provide an inappropriate type of data for the model column.

This is just a more convenient syntax that does the same thing as get_value().

Parameters

column

The model column.

TreeIter<TreeConstRow> Gtk::TreeConstRow::parent

(

)

const

Gets a const_iterator to the parent row of this row.

Returns

A const_iterator to the parent row.
